Proof that there are 7 skies?

The concept of there being seven skies or heavens is a belief found in various religious texts and traditions, including Islam and Judaism. In Islam, the Quran mentions the existence of seven heavens in several verses, such as in Surah Al-Mulk (67:3) which states, "He who created seven heavens in layers. You do not see any in the creation of the Most Merciful any inconsistency. So return your vision to the sky, do you see any breaks?"

Additionally, in Jewish mysticism, the concept of seven heavens is also present in texts such as the Zohar. These beliefs are based on spiritual and mystical interpretations of the universe and are not meant to be taken as literal physical skies. Therefore, the belief in seven skies is a matter of faith and interpretation rather than empirical proof.

There are no scientific or religious proofs for the existence of seven skies. The concept of seven skies is a religious or mythical belief that varies among different cultures and religions.
